Description

A kind of processing ratio of height to diameter is big, the lower center presser device of the poor product of big platform

Technical field

The utility model is related to a kind of automatic moulding machine, and specifically a kind of processing ratio of height to diameter is big, under the poor product of big platform Center presser device.

Background technology

With social development, Mechanical Manufacturing Enterprises gradually replace artificial trend to automate, and more and more set automatically It is standby to be applied to numerous job shops.Automatic moulding machine is also one of them, and is favored by vast foundry enterprise.

Casting or mould need to obtain through over packing, compacting, wherein filling, charging quantity, compacting, amount of compaction are to be related to Can mould meet the important indicator of requirement, filling definition, by pressing plate and sandbox relative movement in template, sandbox and pressing plate it Between formed confined space after, from blasting unit to this space penetrate sand process cry fill.Charging quantity is defined, and equipment is in the state of filling Upper lower platen leaves the vertical range of template top and bottom, is charging quantity.Compacting definition, makes pressing plate to being dredged in sandbox by oil cylinder movement The sand pressurization of pine, so that the process that sand base density is improved in sandbox is compacting.Amount of compaction is defined, and pressing plate is moved from filling state Compaction state is moved, the amount of short transverse change is amount of compaction.

But common forming machine principle such as Fig. 2, for the big product of ratio of height to diameter, or the big product of step difference, A in fig. 2 Drape forming density ratio is very big compared with B drape formings density difference, such as certain product height 150MM, filling sand height 300MM pressures Real 50MM,

A-quadrant compression ratio δ 1== , a-quadrant density improves

B area compresses than δ 2== , the raising of B areal concentrations。

Cause B regions bottom density is improved smaller in view of die wall and factor that sand rubs, so that ratio of height to diameter is big Product on automatic modeling it cannot be guaranteed that sand base density difference is too big after shaping, or shaping so that casting accuracy is uncontrollable, And ratio of height to diameter is big or the poor big product of platform can not be completed on automatic moulding machine.
